Thanks to Boris Steipe, Jim Lemon and Ivan Calandra for replying. I messed up while copying, there are equal number of values for each country. @ Ivan, In case there were different number of values, and we wanted to fill in with 1) NA, or 2) "average of the rest of values" in the missing valu

Re: [R] Generate Variable Length Strings from Various Sources

Hi Rainer, Thanks for the tip. Your suggestion works perfectly, however as per the R Mantra of avoiding for loops, I propose the following this alternate: # number of strings to be created n <- 50 # random length of each string v.length = sample( c( 2:4), n, rep = TRUE ) # letter sources src.

[R] Relative Cumulative Frequency of Event Occurence

Hi, My objective is to calculate "Relative (Cumulative) Frequency of Event Occurrence" - something as follows: Sample.Number 1st.Fly 2nd.Fly Did.E.occur? Relative.Cum.Frequency.of.E 1 G B No 0.000 2 B B Yes 0.500 3 B G No 0.333 4 G B No 0.250 5 G G Yes 0.400 6 G B No 0.333 7 B B Yes 0.429 8 G G
